Abstract
A device and method are provided for determining the amount of solid material dispersed in a liquid. The device and method allow for the passage of a beam of light into the liquid containing the dispersed solid through the meniscus of a gas-liquid interface window which is formed. The meniscus is periodically or continuously renewed by a flow of gas. The scattering or transmission of the light through the liquid is then detected and provides a measurement of the amount of solid material dispersed in the liquid.
